Supervised Alarm / Relay / Power Expansion Unit
Cabinet Mounting
Inspect the mounting surface around the proposed installation
site. The mounting surface must be capable of supporting 17
pounds (7.6Kg) plus any additional weight of the installation
hardware.
CAUTION
Use only suitable mounting hardware for the
type of wall construction encountered.
Disconnect the battery, preferably by sliding off the “Molex”
connector on the Charger Board, then carefully remove the
backup battery and its associated clamp by removing three
screws. Please save these screws for later use.
1. Determine the Expansion Unit cabinet mounting location.
Keep in mind that conduit will be used to connect the Ex-
pansion Unit to the Super Two Access Control Panel. If
the tops of the enclosures are kept on the same line, the
conduit connection will be simplified. The Expansion
Unit will normally be to the left of the Super Two Access
Control Panel.
2. Mark the four mounting holes against the mounting sur-
face using the Expansion Unit cabinet as a template, or
using the measurements provided in Figure 6.
NOTE: Mark the small oval portion of the cabinet screw
holes (see Figure 7, Detail A and B, below).
3. Place the Expansion Unit cabinet out of the way.
4. Drill pilot holes to the required depth and size for the
mounting screws.
5. Insert the top two mounting screws into the wall. Leave
approximately one quarter of the screw's length protruding
from the wall.
NOTE: Do not tighten screws completely at this time.
6. Place the Expansion Unit cabinet over the mounting
screws. Secure the Expansion Unit cabinet to the mount-
ing surface using the two lower screws, and then tighten
the remaining length of the screws.
7. Re-install the back-up battery and bracket using the
screws that were saved as advised above. Slide the Molex
connector back into its place.
NOTE:
Because of the Low Battery Voltage Disconnect fea-
ture, the Expansion Unit 12 volt output will not start to
operate until Mains (AC) power is connected.
